1. A data recording/reproducing apparatus comprising:
a recording medium having a recording area to record therein data;
a support device disposed in a predetermined position relationship with the recording medium;
a first probe, which is supported by the support device, for recording data onto the recording medium or reading data recorded on the recording medium;
a second probe, which is supported by the support device, for recording data onto the recording medium or reading data recorded on the recording medium; and
a displacement mechanism for relatively displacing the support device with respect to the recording medium,
a part of the recording area of the recording medium having a position control area which corresponds to a part or all of a specific range where a tip portion of the first probe can be relatively displaced along with the relative displacement of the support device or which corresponds to a broader range including said specific range, first position information being recorded in a part or all of the position control area,
the recording area of the recording medium being divided into a plurality of areas which are arranged in a matrix, the position control area being at least one of the division areas or a part of at least one of the division areas,
the position control area being formed in a central portion of the recording area of the recording medium.
